Our Thor Compass on the Transit HD chassis had the 3.2l 5 cylinder. It was awesome especially in that particular chassis/weight class.
Not much CCC...but the Compass isn't that big to begin with. And that lack of capacity affected it's towing ability.
But...the mileage, convenience, and power were great. Only drawback was the need to find a Ford dealer with a heavy lift. Not all Ford dealers have them and they won't work on them unless they can lift them.
I see where Thor has dropped the diesel, but Ford is still making them with the new 2.0l diesel according to Google. However, that little 2.0l engine doesn't have the carrying capacity of the 3.6l gassers. Doubt we'll see that diesel in an RV.
